Abstract

Elektrische Installationsanlage zur Speisung von Ver­ brauchern (1), insbesondere mit elektronischen Bauteilen, aus einem Netz, die durch Fehlerstromschutzschalter (2) und in einem Nebenzweig an Erde angeschlossene Überspannungs­ ableiter (3) ohne eigene Abschaltvorrichtung geschützt sind, wobei der Fehlerstromschutzschalter netzseitig vor einem zu­ geordneten Überspannungsableiter angeordnet ist und auf diesen hinsichtlich einer Zeitverzögerung von 10 ms und ver­ träglicher Stoßströme von mindestens 5 kA, 8/20 µs Impuls - abgestimmt ist. Erfindungsgemäß ist vorgesehen, daß jeweils der Fehlerstromschutzschalter (2) für eine Stoßstromfestigkeit bis maximal 30 kA ausgelegt ist und in etwa der Beziehung ge­ nügt: Electrical installation system for feeding Ver users (1), in particular with electronic components a network by means of residual current circuit breakers (2) and in an auxiliary branch connected to earth arresters (3) are protected without their own shutdown device, the residual current circuit breaker on the network side in front of you orderly surge arrester is arranged and on this with regard to a time delay of 10 ms and ver inert surge currents of at least 5 kA, 8/20 µs pulse - is coordinated. According to the invention it is provided that the residual current circuit breaker (2) for surge current resistance is designed up to a maximum of 30 kA and approximately in the relationship ge suffices:

Stoßstromfestigkeit des Fehlerstromschutzschalters ist gleich Anzahl der Überspannungsableiter (3) gegen Erde, mul­ tipliziert mit 5 kA. Surge current resistance of the residual current circuit breaker is equal number of surge arresters (3) to earth, mul multiplied by 5 kA.
